摘　　要：将膨胀石墨(EG)-氢氧化铝(ATH)-甲基膦酸二甲酯(DMMP)复合阻燃剂分别与锡酸锌(ZS)、羟基锡酸锌(ZHS)进行复配,制备出阻燃硬质聚氨酯泡沫(PRUF)复合材料,采用热重分析、极限氧指数(LOI)、锥量测试、扫描电镜(SEM)及能谱(EDS)测试分析了阻燃PRUF的阻燃和抑烟性能,通过压缩强度、比强度、表观密度和导热系数研究了其物理-机械性能。结果表明,ZS、ZHS能起到良好的协同作用,有效提升PRUF的阻燃抑烟性能,当ZHS质量分数为4%时,PRUF的阻燃和抑烟性能相比原样提升最显著。The flame retardant rigid polyurethane foam(PRUFs)composites were prepared by compounding expanded graphite(EG)-aluminum hydroxide(ATH)-methyl phosphonic acid two methyl ester(DMMP)composite flame retardant with zinc stannate(ZS)and zinc hydroxyl stannate(ZHS),respectively.The flame retardancy and smoke suppression properties of flame retardant PRUFs were analyzed by thermogravimetric analysis, limiting oxygen index(LOI),cone test, scanning electron microscope(SEM)and energy dispersive spectroscopy(EDS).The physical mechanical properties were studied by compressive strength, specific strength, apparent density and thermal conductivity.The results show that ZS and ZHS can play a good synergistic role and effectively improve the flame retardant and smoke suppression performance of PRUFs.When the addition of ZHS is 4%,the flame retardant and smoke suppression performance of PRUFs is significantly improved comparing with the original.
